| 4805 are available via the stacked serial connectors on the mother board in | |
| 4806 the case of the FR400 CPU board, and via serial connectors present on | |
| 4807 the other supported CPU boards themselves. The topmost port is the | |
| 4808 default and is considered to be port 0 by RedBoot. The bottommost | |
| 4809 port is serial port 1. The default serial port settings are | |
| 4810 115200,8,N,1. The serial port supports baud rates up to 460800, which | |
| 4811 can be set using the <command>baud</command> command as described in | |
